In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:The formula connecting u,v and f for a spherical mirror is valid only for mirrors,whose sizes are very small as compared to their radii of curvature. Reason:Laws of reflectoin ar strictly valid for plane surfaces,but not for large spherical surfaces.

A sphere of charge + Q is fixed in position. A smaller sphere of charge + q is placed near the larger sphere and released from rest. The small sphere will move away from the large sphere with decreasing velocity an inreasing acceleration, decreasing velocity and increasing acceleration, decreasing velocity and constant acceleration, increasing velocity and increasing acceleration explain, which of the following statements is correct?

Read the given passage and answers following questions : In multi-molecular colloids, the colloidal particles are an aggregate of atoms or small molecules with a diameter of less than 1 nm. The molecules in the aggregate are held together by van der Waal's forces of attraction. Examples of such colloids include gold sol and sulphur sol. In macro-molecular colloids, the colloidal particles are large molecules having colloidal dimensions. These particles have a high molecular mass. When these particles are dissolved in a liquid, sol is obtained. For example: starch, nylon, cellulosc, etc. Certain substances tend to behave like normal electrolytes at lower concentrations. However, at higher concentrations, these substances behave as colloidal solutions due to the formation of aggregated particles. Such colloids are called aggregated colloids. How many types of colloids exist ?
